The ProjectProject Scope Objectives

• To create a solar desalination system utilizing an inflatable parabolic reflector called the Solar Sausage

• To create a system that can be easily mass produced at low cost.

• Produce drinking water with a saline concentration less than 100 ppm

• Support a family of 5

• Minimize cost

• Create a user friendly system that can be easily transported and constructed

Solar Sausage

Figure 1: Cross-Sectional view of the Sausage

• Inflatable parabolic reflector in the shape of a sausage

• Made of a clear membrane and a Mylar reflective membrane

• When inflated the reflective membrane separates the Solar Sausage into two sections

• Upper Pressure: o Lower Section is less than the top

The System: Storage Tank• Storage Tank will be a five

gallon bucketo Readily available filterso Approved by U.N for storing watero Height: o Diameter:

• Bucket will sit on the Storage Tank Platform o Will be above the stand

• Saline water piping systemo A ball valve is used to control the flow

The System: Storage Tank Configuration

• The piping system is used to secure the bucket to the platform

• A flare nut is used to lock everything in position

• Two rubber O-rings are make the storage tank water tight

The System: Sun Tracking • Straps

o Glued to sides of Solar Sausage (shown in red)

o Crossed beneath Solar Sausageo Attached to weighted bar underneath

• Converts linear translation to rotational motion

• Direction of rotation of Solar Sausage dependent on bar motion o Ex. Moving bar to the right produces

counterclockwise rotation of Solar Sausage

The System: Operation


12

Fill water storage tank with saline water to filter out debris

The System: Operation


13

Open valve to fill trough with filtered water

The System Operation


14

Use the Pressure Regulation System to create focal point and heat the trough



15

Water vapor rises into the dome, condenses then collects in the channels



16

The gradient drives the water to the collection pipe. The desalinated water is collected in a container of choice by the operator

Desalinated Water

The System: Maintenance• Daily Maintenance

o Clean Trough of all saline build upo Clean Condenser of all build upo Check Solar Sausage for any tearing

• Weekly Maintenanceo Rinse saline water filter of all dirt and debriso Clean desalinated water containerso Tighten all connections on the pressure regulation systemo Clean Saline Water and Desalinated Water piping systems of all build up

Testing: Future Testing• Flash Distillation

o Valve placed at to allow a slow-drip into heated trough

o The evaporation rate will be calculated. This will be repeated in till Flash Distillation is no longer possible

• Batch Distillationo The trough will be filled with , and the

time for it to evaporate will be measured

• Focal Point Concentrationo Focal point width: -o Procedure to maintain width

• Sun Tracking Systemo Procedure to track the sun

• North-South alignmento Adequate rotation value and

frequency• i.e

Testing: Safety & QualitySafety Procedures Water Quality

• Heat-Resistant gloves will be worn during testing

• All temperatures will be taken at a distance with a Pistol-Grip Infrared Thermometer

• Trough and Condenser will be allowed 30 minutes to cool after testing before

• The saline concentration of the drinking water produced will be measured

• Measures saline concentration

• ExStik II Salinity Meter will be used o 2% Accuracy
